Need ID help of breathers

I'm hoping someone can identify the valve cover breathers in the pics. The year is 1966. All of the breathers I have seen have a flange on the base to attach the breather to the cover and these don't have a flange.any help is much appreciated thanks.

 

The ones from the mid 60s didn't have a flange. They were held on by screws through the valve cover into the breather.




The earlier breathers for the oil pan had the flanges.

If you are tying to duplicate the hairy Olds, that could be a problem. Finding 8 of those could be a chalenge.

 

they look like Eelco to me

 

I'll be looking to see if I can find Eelco breathers on the net. I would need 16 of these breathers. I really only need one and I could cast them pretty easily.

 

My alquist breathers are not flanged, but they are straight, I don't know if almquist made 90 degree breathers
